Does she inherit the Duchy that she's Duchess of?? Sort of like Eleanor of Aquitane?

1b) Jaime Alvares Pereira de Melo, Duque de Cadaval (San Sebastian 21 Jan 1913-Estoril 31 Jul 2001); m.1st London 29 May 1936 (div) Antoinette Louise Schweisguth (Epinal 6 Aug 1899-Paris 22 Nov 1982); m.2d Lausanne 3 Feb 1965 Claudine Tritz (b.Guistreham 4 Aug 1943); since the death of the Duque the succession to his titles was in dispute among his daughters; one reported said that the Duke of Braganza awarded the title to the third daughter; a subsequent report said that he recognized the eldest daughter

Apparently Dom Duarte doesn´t recognise marriages done by the Portuguese state but only those that are done in church, hence he supports the claim of Diana instead of that of Duchess Rosalinda de Cadaval.

Diane has featured in several Point de Vue issues the last months, she seems to love publicity as much as her husband-to-be does. I believe he previously dated Countess Elisabeth d´Udekem d´Acoz, sister of Crownprincess Mathilde, who is now Marchesa Pallavicini.

Well, I asked a Portuguese friend of mine and he said that she/the family isn´t that wealthy according to him. Most of what she owns is tied up in real estate and art. She has one or two estates I believe, she was recently photographed by Point de Vue with her mother at one of these estates. Her sister Rosalinda is the weathly one, as she married a Hermes. The latter is now sometimes referred to as Duchess od Cadaval-Hermes, rather odd combination.

Diana is the eldest daughter of the late Duke of Cadaval with his second wife Claudine Fritz, although Rosalinda (married to Hubert Guerrand-Hermès, the heir of the House Hermès) is actually the eldest daughter of D. Jaime, but born from his first marriage (which was not religious, but a civil wedding).

There was a dispute on the succession to the title, since it was Diana (born from the Catholic marriage) and not Rosalinda (born from the first marriage) to inherit the title. At the time, the Duke of Bragança had to decide on who would inherit the Duchy of Cadaval (since Portugal no longer has noble titles, they're not a matter decided in courts and all things related to it are decided by an entity named Conselho da Nobreza, which has its highest figure in the Duke of Bragança). The final decision was based on D. Jaime's wish, since he made it clear he wanted Diana to inherit the title.

I'm not sure about the details of the agreement that was reached between the parts, but, from what I read in the press, the Duke of Bragança considered a kind of "salomonic" sentence, dividing the various titles of D. Jaime (Duke of Cadaval, Marquis of Ferreira, Count of Tentúgal) among his 4 children.

Diana Mariana Vitória Álvares Pereira de Melo is the 11th Duchess of Cadaval. She was born in Genève, in 1978, as the first daughter of D. Jaime Álvares Pereira de Melo (the 10th Duke of Cadaval) with his second wife, Claudine Marguerite Marianne Tritz. She belongs to the second most traditional family in Portugal (which is a colateral branch of the Dukes of Bragança).

Was Diana´s father estranged from his two eldest daughters? Did the second wife influence her husband to denounce his first two children maybe?

I believe his wife took an important role there(Duchess Claudine is a very strong woman)... and yes, Rosalinda was not happy at all with the decision, I can say that.

Last February, after the couple appeared together on "Point de Vue" for the first time, the magazine published a letter from the lawyer of D.ª Rosalinda, where she expressed her annoyance for the treatment given to her sister as "Duchess of Cadaval", assuring that she (D.ª Rosalinda) was actually the 11th Duchess of Cadaval, 13th Marquesss of Ferreira and 23th Countess of Tentúgal (titles she claimed then were given to her by the Duke of Bragança).

Afterwards, the magazine asked D. Duarte for a clarification and he explained that D. Jaime wanted Diana to inherit the Duchy, so he promoted a family meeting, at the end of which D. Duarte decided to execute D. Jaime’s will: Diana received the title of Duchess of Cadaval; Rosalinda was named Marquess of Ferreira and Countess of Tentúgal in addition to the courtesy-title of Duchess of Cadaval-Guerrand-Hermès.

D. Duarte also explained that the Duchy of Cadaval is not a title of automatic succession, so, once Diana passes away, it will be the head of the Royal House (probably Prince D. Afonso) deciding who will succeed to D.ª Diana: her child or any other member of the family.

Thank you for the pix i had wondered how she looked like.
After the wedding we can expect in Point de Vue some news from her (unless of course Carla Sarkosy has a little cold, they would be o bliged to put her on the cover then instead !)

Diana belongs to a colateral branch of the House of Bragança, descending from D. Nuno Álvares Pereira de Melo (1638-1725), who was the closest male relative to King D. João IV, and therefore the second most important person in the kingdom.
Nuno Álvares Pereira recieved the Duchy of Cadaval in 1648.

I was wondering, why is the succession in this duchy not automatic? Is that only in this case as the succession is not clear or was that always the case? And if Diane clings onto Dom Duarte's decision, why doesn't she respect it that her elder sister got the other titles (it seems Diane uses them too). She stole the most prominent title so she might just as well leave something to her elder sister.

I don't envy the Duke of Braganca in this matter though, whatever decision he took or takes it will never be satisfying for all parties involved.
